OPHTHALMIC Ii'IOUNTIIIG.

Application filed December 23, 1919.

To all whom it may concern.-

Be it known that l, l nens-union Airrnun STEVENS, a citizen of the United States, a. a resident of Providence, in the county 0 Providence and State of lslhode island, have invented new and useful improvement in Ophthalmic Mountings, of which the following is a specification:

The present invention relates to ophthalmic mountings and mo particularly to eycglass mountings of the type in which the lens rims are split at the point of juncture with the bridge. The term eyeglasses will be employed in the claims as synonymous with opl'ithalniic mounting.

[in object of the invention is to siiupli v and improve the construction of eve-glint and guard mountings.

in present-day eyeglass mountings, usu allv constructed, the guards are mounted in close proximity to the ends of the bridge and so interfere with the operation of adjusting the bridge.

A. further object of the invention is to provide an improved ophthalmic mounting of the above-described character in which the bridge may be adiusted without intor- 't'ei'ence from the guards.

To this and, a feature of the invention contemplates an eyeglass frame in i ch the bridge and the guard are mounted in close proximity to each other, one upon each of the end pieces of the lens rims so that, u pen separation of the end pieces, .6 guard will be moved out of the way of the pc (ion of the bridge which it may be desired to edjust. As a further if ure, the bride ci'uistructed to enter a recess in the :21 cud piece so as to prevent relative wove most of the guard and the bridge after the. parts are secured in assembled relation.

Another object of the invention is to v ride an improved eyeglass mount a in which the relative positions of the rim, the bridge and the guard may be readily altered (ll'llll'lg the process of manufacture.

iVith this result in view, a feature of the invention resides in mounting the end piece upon the end of the rim at any desired angle.

With these and other objects in view, as will be made clear as the description pro- Serial No. 346,953.

cecds, the invention consists of the improved ophthalmic mounting hereinafter described, illustrated in the accompanying drawings and defined in the appended claims.

In the drawings, Fig. 1 is a front view of an ophthalmic mounting illustrating a preferred embodiment of the invention; Fig. 2 is a rear View of the same, showing one of the lens rims open; Fig. 3 is an'enlarged fragmentary view, partly in section, showing the parts in assembled relation; Fig. 4 is a sectional view taken upon the line %.4 of

3, looking in the direction of the arrows; Fig. 5 isan enlarged view, partly in section, of the ends of the open lens rim shown in 2; Fig. 6 is a View similar to Fig. 3 showing the ends of the rim in partly assembled relation, before the insertion of a lens; Figs. 7 8 and 9 are views of modifications; Figs. 10 and 11 are modifications of the structure shown in Fig. 4:; and Fig. 12 is a view illustrating a process of manufacture.

The invention is shown in its preferred form in Figs. 1 t0 6 inclusive in connection with an eyeglass frame comprisingtwo split lens rims 2, each enclosing a lens 4 and connected together by a bridge 6. Guard levers 8, supporting nose guards 10 and finger pieces 12, are pivotally mounted about bearings 13 provided upon posts 14 in close proximity to portions 16 of the bridge and are actuated or swung about the bearings 13 by the customary springs 18. The lens frames, guards and other mechanisms at the sides of the bridge are right-and-left-hand duplicates.

The end pieces 20 and 22 of each rim are constituted of flat, contacting plates, as shown. These plates are provided with alined or substantially registering screwthreaded openings 2st and 26 of the same diameter adapted to form a continuous threaded passage when the end pieces are in contact with each other. The passage registers with the opening in the lever 8. The post 1 is shown as a connecting screw, provided with aterminal threaded portion 28 adapted to enter the screw-threaded openings 2d and 26 to secure the end pieces 20 and 22 togetherv The bearing portion 13 of the post is of larger dialneter than the diameter of the opening 26, thus forming an annular shoulder for engaging the end plate 22 and for maintaining the latter in contact with the end plate 20. The single post l t thus serves, as shown more particularly in l i 7, to secure the end neces of the rim together and to secure the guard lever to the rim. The tension of the rim up on the end pieces Will ordinarily be sufficient to prevent the accidental loosening of the post i l, but the terminal portion 28 may be spun over upon the end piece 20 in a manner Well known to serve as en additional means for preventing such loosening. it is nal portion 28 or somewhatlonger diniei sions than shown in Fig. 7, as illustrated 1.1 Fig. 3, to permit the use or" a check nut 30. The use of the longer post is attendant with an additional advantage in that after the bridge has been adjusted to the personal demands of the wearer, the end pieces need never again be further separated t ran through the short distance indicated in Fig.

6, the long post still retaining control or" both ends. This degree of separation su fioient for the purpose of replacing broken lenses.

As the bridge is not intended to rest noon the nose, the guards alone being depended upon for supporting the eyeglass, the pertions 16 of the bridge may be lent abr iptly away from their supporting end pieces 20. substantially parallel to tangents the rims at the split ends of the rims. abruptness of the bend serves a duible purpose. First, a larger space is provided for the Wearers n se than would be the case it the bend were {gradual and this, of vourse,

results in short ning the pupillary distance.

The same mounting, secondly, adaptel to the personal requnein .nts or a Wnen the degree of adju... inont required considerable, the operatioi is ende diliieult and awkward by tl the ghzil'tl levers near to the is desired to adjust.

ie parts which it fro-:ording to the present invention. the bridge is secured to one end piece 20 one the t parts of the bridge which adjust. This separation may be eltected by reversely rotating the ost 14luntil the terininal screw-threaded portion :28 ha screwed out of the open ng this feature of the invention is concerned. is is obviously immaterial Whether th l lever is 01" the spring-pre ed,

To eliin'iiate this tendency, the end piece 20 oii set at L0, so that the offset or projecting; portion may overlap the end piece 22 and enter the recess 38. The portion 4-0 engages the walls of the recess, locking the end pieces together. its the portion 40 constitutes the terminal. portion oi? the bridge, which is thus shown as continuous or integral with the end pie e 20, the bridge, in effect, coacts with the end piece 22 to prevent relative movement of the end The guard lever of Figv 8 be similarly recessed, thebridge entering the recess to prevent relative movement of the guard with respect thereto.

The present invention lends itself: cqua. readily to the production of ophthalni mountings the bridges and the guards of which be mounted directly in the plane of the lens or forward or back 0t this plane. This feature of the invention will be easily understood by reference to e, 10, ill and 12.

It will conduce to a clearer understanding of these figures to state that the invention is illustrated in connection with the compositezylonite-and-ntietal frame of Patent l lo. 1,293,282, l eb. d, 1919, the zylonite element of the rim 2 being indicated at and the metal element at The end pieces 20 and 22 are soldered or otherwise secured to the ends of the metal element se l. The end pieces are or'qinally of the shape shown in full lines Fig. 152, which is a plan view, and comprising, in effect, two substantially cylindrical portions 46 and 4-8, secured together at 50. The cylindrical portion 48 may be bevelled. at 52, to produce a finished effect, shown in Fig. 5.

"to produce a mounting the bridge and ;he guards of which shall be approximately n the plane of the lenses, the cylindrical iortion it} should be out along; the lines 5st, and 58 (Fig. 12). An end of the metal element ley then be soldered. or other-- wise secured to the faces oi: the end piece alone; the lines 56 and 58. the zylonite eleinen being secured as shown in Fig. 4. T e recess (8 should be cut out along: the

A l i i i ii c (30, Similarl if the cylindrical oortion till an inset structure may be produced, as shown in Fig, 11; and the outset structure of Fig. 10 may be obtained by cutting along the lines .68, 70 and 72. The end piece may thus be secured to the lens rim at variable angle. The corresponding variably positioned recesses 38 of Figs, 11 and 10 may be obtained. by cutting along, the lines 7% and 76, but in practice it is :tound that the recess 38 may in all cases be cut along the line 60 and the bridge portion l0 may be bent a little in one or the other direction so as to conform. vi li-ether the structure of Fig. tbe employed, or the inset of Fig. Ill or the outset of Fig. 10, the bridge will cooperate with the end piece 22 to securely lock the end pieces 20 and 22 against pivotal movement.
